uacnnmroa nxme rum cones.

a plicat on filed Logan}, 1921'. Serial No. massa- To allwlw'm it my camera: Be it known that I, JOHN Errnnn, a c tizen of the United States, residing at Ph1ladel hia, county of Philadelphia, and State ennsylvania, have invented a new and useful Improvement 'in Machines for Makingra er Cones, of which the followmg 1s a ll, clear,'and exact description, reference bein had to 'the accompanying drawings, whic forma partof this specification.

My invention relates. to paper cones for use as spools for holding yarn in textile mills. The object of my invention s to make said cones, in a continuous process, from a roll of paper. The invention comprises a machine adapted to efl'ect such ob- 'ect. In the embodiment of my inventlon erein disclosed, suchmachine includes means for feeding paper from a roll; means for applying gum to a portion of the paper, leavingungummed the part that forms the inner surface of the cone; means for trimming one edge of the paper, removing the flims beveled edge and giving it a contour whic 1 will readily enter the slot in the comcal mandrel used in making the cones;

means for cutting the blank to form a cone and entering it into the mandrel; means for winding the blank aboutthe mandrel, meanwhile applying pressure thereto to insure adhesion of the gummed surface; means totrim the ends of the cone, finishing it to specified length; and means for discharging the finished cone.

.Anyone skilled in the art will fully understand and appreciate the novel features and advantages of my invention from the following description of my machine, in con- .n'ection with the accompanying drawings, in

which: a

The roll of paper a is mounted in brackets below the machine table I), as shown in- Figure 3, and carries a pulley at one end provided with a spring tension cord 0 for imparting resistance to unwinding. The paper is led upward from the roll and over a rod d at just about the table level. Thence it passes between the large rollers and f, around roll f against which it is held by a spring-pressed roller 9, up and around a roller 72., supported: on brackets at aheight above thetable, and down again'and under a roller 5, which delivers the paper at the working level of the cutting knives. The elevated position of roller h is adjustable and is for the purpose of allowing sufiicient time for the gum to set on the paper. I

Rollers e and f are intermittently driven as will be hereinafter described. The lower one, roller 6, is the gumming roll and dips into a bath 11 in the table carrying liquid gum for the purpose. It is not desired to. gum the entire surface of the paper, however, as that would make the finished hollow cone have a gummed inner surface. To avoid this, roller 6 has a cut-away portion 6, shown clearly in Fig. 1, which does not contact with the paper and is made of such shape as to have a triangular portion of the surface, represented by the angle 6 on the blank shown in Figure 2, uncoated with gum.

The paper passes from roll 2', over a cutting plate 7' and between the feed rolls 7c and k, which are intermittently driven with rolls 6 and f. While the rolls are stationary and the paper lies on the cutting plate j,'the

irregular cutting blade l is brought down,.

the driving mechanism. 4

the paper is fed forwar and deposited on the turn table t beneath the semi-circularv cutter .8. A pivoted holding frame it is then swung down to clamp the blank upon the turn table. The cutter a is then caused to descend and cut the blank as shown in Figure 2.

Turn table it is then caused to. turn throughout an arc of about 90, from the osition shown in Figure 1 to that shown in ig. 8. As it gets to this position, a horizontal finger '0 on the holding frame overrides a pin on the lower end of a rod w, Figure 9. en the turn table has finished its motion, and the irregular cut edge Z-' of the. paper blank held thereon is entered into I I slot 2: in the conical mandrel y, this rod 10 is caused to rise, lifting the holding frame u and releasing the blank.

As will be seen in Fig. 6, the slot in the conical mandrel is a mere slit :1: for about half its length, narrow enou h to firmlv hold the edge of the paper. 'l e remainder of the slot, at thesmall end of the cone, is flared wide forthe reception of the paper. When the paper is first presented to it, the mandrel is in a retracted position and the projecting portion of the paper freely enters horizontally into the flared portion of the slot. The mandrel is then moved lengthwise by its cam 40 to the relative position shown in Fig. 6, which causes the rojecting edge of the paper to slide into t e narrow portion w of the slot where it binds suficientl to hold for wrapping about the mandre Atthe same time the turn table is given a slight backward turn partly withdrawin the edge of the paper so that it will exten less deeply into the mandrel, leaving just enough lap to hold the paper for wrapping as desired, and avoiding the objectionable triangular shaped lap commonly formed by machines now in use.

At this time the holding frame is lifted as (previouslydescribed, releasing the blank, an the mandrel is given a rotary motion, wrapping the paper blank about it to form the desired cone. As before stated, the portion of the blank forming the first wrap about the mandrel is free of gum, but the succeeding two or more wraps are gummed on the top or inner surface and adhere to the first wrap and to each other to form a solid cone of several thicknesses of paper. A wiper 12 is provided for pressing the wraps together on the mandrel. as they are being formed. Wiper 12- extends parallel to the conical surface as shown in Figure 5, and is carried on the end of a lever 13, the other end of which, as seen in Figure 10, is spring-held against a cam 14 on shaft r. Cam 14 allows the spring to press wiper 12 against the cone while the-latter is making ten or adozen revolutions so that the paper .of slide 22. Just at the time the mandre During these extra rotations the paper cone is cut to length at both .ends b cutter wheels 15, moun -E to rotate free y on a frame 16 vertica slidable in a standard 17 on table E). 'llo t is end a lever 18 is pivoted to said standard, one end of said lever carrying an adjustin screw 19 which contacts with the top of rame 16, and the other end of said lever being actuated by a cam 20 on shaft r". @utters 15 normally springheld up out of action, and at the right moment cam 20 raises its end of lever 18 which causes frame 16 carrying the cutters to descend into the conical surface of the mandrel, one near its point, t M '11 0d the tip of the paper cone, and the other near the large end, acting similarly.

There are circles of fibre inserted flush mandrel and paper' cone causes the cutters to revolve as soon as they me contact and p the result is a clear ished out at both ends of the paper cone, which is now ished.

The mandrel then a: a turning,'the cutters are raised and the wimr lowe out of action, when themandrel is withdrawn longitudinally through its slide 32 and cone discharge band '23. This hand slides in the cylindrical portion of the spindle and is supported by rods 24 slidable in the cas' 1- .1:

starts to withdraw, one of these rods is given a forward kick b a lever 25 acted onby a cam 26 on shaft ras shown in Figure 1. This kick gives band 23 a preliminary forward motion against the large end of the cone, causing it to loosen from the mandrel. In the following withdrawal of the mandrel the finished paper cone falls through an opening in table 5 into a chute or receptacle not shown.

All the operations of the machine are driven from a shaft 30, which may receive its motion from a counter shaft or reducing gearing, as most convenient, and ma ca a hand wheel for turning it over'if esire,

Shaft 30 operates shaft 1" by bevels 31 and at its opposite end shaft 7* operates through bevels 32 to turn shaft 7, so that dull the steel cutters. The turning of e is a pinion 36 carried by the turning post of turn table t. A' sprin 37 holds arm 34 against cam 33, and on t e low part of the cam, as shown in Figure 5, the turn table is held in its normal position for receivin the end of the paper strip. When the big part of .cam 33 acts on arm 34, rack 35 is drawn over, which turns pinion 36 and the turn table is turned to deliver the cut blank to the mandrel.

For operating the mandrel longitudinally, sha-ft carries a cam 40, which acts on an arm 41 pivoted to the frame of the machine below table b and extending up therethrough. The upper end of arm 41 is linked to an arm 42 depending from a standard on table 6. Ann 42 is likewise connected by a link 43 with a sliding rod 44 mounted in brackets to move parallel with the table. A

block on rod 44 turnably carries the end of spindle 45 carrying mandrel y. Thus cam 40 acts through arms 41 and 42 to slide rod. 44 and with it the mandrel, at the proper moment for discharging a paper cone.

The mandrel is intermittently rotated from a gear 46 on shaft 7'' provided with a toothed portion and a blank portion. Through reducing gears 47 this intermittent gear acts upon a pinion 48 splined upon lever 52 resting on the low part of a camspindle 45 of the mandrel. The arrangement is such that the spindle 45 may be moved longitudinally through pinion 48 to project the mandrel to .receive the edge of the blank, whereupon the toothed portion of gear 46 acts upon gearing 47 to turn pinion 48 thereby rapidly revolving the spindle and mandrel.

As before stated, when the paper blank is fed to the mandrel, holdin frame to is raised from the surface of t e turn table by 'rod w lifting up finger 1). There is a .latch 50 on the under side of the turn table forholding the frame in open position when it has been thus raised, a spring 51 connecting the latch and the frame acting to both raise the latch and draw the frame down. While the paper blank is being wound onto the mandrel, the turn table is returned to its initial position, the holding frame being held open by the latch. In this initial position of the turn table, the end of the latch underrides one end of a lever 52 pivoted to a fixed support, the other end of 53 on shaft 1*. At the proper time, when the paper has been fed onto the turn table and the feeding machanism is at rest, -cam 53 acts to turn lever 52 to open latch 50 and spring 51, together with its own weight,

brings frame u down to clamp the paper onthe turn table preparatory to the semi-circular cutting action.

Continuously revolving shaft 1' carries the cam g for operating the irregular edge cutter Z. Shaft 7* also carries a facial gear 55 provided with teeth for only a portion of its periphe to intermittently drive the gumming an feed rolls. At the time desired to.

feed the paper, the tooth portion of gear 55 acts upon a pinion attached to a gear 56 to rotate this gear. Gear 56 meshes with a gear 57 on the shaft of roller f, and gear 57 is in turn in mesh with a gear 58connected with the gummin roll 6. Thus at the proper time these .rol draw the paper from the aperroll a. c

A sp oc et wheel 60 on'the. shaft of roll f is conn cted by a chain with a sprocket 61 on the shaft of feed roller is. Feed rollers k and k are connected at their opposite ends by equal ars 62 so that they are both rotated positively to feed the paper at the Semi-circular cutter s is carried on ver tical posts 63 slidable in a fired supporting frame 64 arranged above the turn table If, and is normall held in upper position by springs 65. T e cutter is lowered to erform its cutting operation in the following manner.

. A horizontal shaft 66 is supported in bearings 67 in the u per part of frame 64. Discs 68 on this sha t'have camways 69 in their opposing faces, wherein travel rollers 70 mounted on guiding yokes 71 carried by posts 72 mounted on cutter 8. Thus the turning of shaft 66 lowers and raises 'yokes 71 and with them the semi-circular cutter s.

A hand wheel 73 may be provided on shaft 66 for turning the mechanism over, but it is normally driven by a ar 74 connected b a train of, gearing 75 with a gear 76 on sha t r. Therefore, shaft 66 is continuouslyturnin and the movement of cutter s is determined by the sha e given cam slots 69.

There is a cam 77 on shaft 66, which op-' erates on one end of a centrally pivoted lever 78, the other end of which actuates vertical rod to, against its s ring. When lever 78 is on the high part 0 cam 77, the pin on the portion affording a ready means of entering the blank and the narrow portion enabling the mandrel to grip a narrow inserted edge of the blank preparatory to wrapping.
